The name "titanium" is derived from the Titans of Greek mythology, symbolizing the strength and durability of this metal. Discovered in 1791 by William Gregor and independently in 1795 by M.H. Klaproth, who named it, titanium is the ninth most abundant element in the Earth's crust. Its exceptional properties, such as high strength, low density, and resistance to corrosion, make it invaluable in aerospace, medical implants, and many other industries. The mythological naming reflects human fascination with the material's superior qualities, aligning it with the Titans' legendary might.

Resin pellets, also known as nurdles or plastic granules, are small plastic particles typically used as the raw material in the production of plastic products. They are produced in a myriad of colors and compositions, tailored to the specific needs of manufacturers. These pellets are melted and molded into various plastic items through processes like injection molding, blow molding, and extrusion. Despite their crucial role in the plastics industry, they pose significant environmental risks if not properly managed. Accidental spills during transportation or handling can lead to ocean and beach pollution, affecting marine life. Efforts are ongoing to mitigate such spills and enhance recycling to reduce the environmental footprint of resin pellets.
